Canterbury police are calling for the public's help in order to identify a man in relation to an attempted abduction.
The incident took place on December 5, 2015 around 10pm at Coes Ford.
"A dark-coloured station wagon travelling south along Lake Rd is understood to have slowed down and travelled next to the victim, who had left friends to go the toilet block," Detective Senior Sergeant David Harvey says.
"The driver and sole occupant called to the victim through the open passenger window, telling her to go with him. He then stopped the car and approached her. The victim made it clear that she would not go with him and walked away from the man," he says.
The man grabbed the woman's wrist and pulled her towards the vehicle before she used self-defence techniques and ran back to her friends, police say.
The man is described as European, approximately 175cm tall, in his mid- to late 20s and wearing a sleeveless top.
Canterbury police want to hear from anyone in the area at the time of the incident or anyone who saw a dark-coloured station wagon travelling along Lake Rd in the vicinity of Coes Ford.
